Start here: https://peo.gov.au/ for basic explanations in how things work here.
Also try last year's Vote Compass: https://votecompass.abc.net.au/ That will help you map your values to how they align with the political parties - or at least what the parties say they'll do
When it's time to vote, go to the actual websites of the parties and read about their policies. Don't rely just on their names as they can be misleading. Do the vote compass every year and that will help you organise your thoughts on the parties.
You don't necessarily need to read the news to form an opinion on parties, but do pay attention to fact checkers and the like, for example: https://www.abc.net.au/news/2023-10-13/fact-check-jacinta-nampijinpa-price-closing-the-gap-place-race/102966826?utm_source=abc_news_app&utm_medium=content_shared&utm_campaign=abc_news_app&utm_content=other. Pay attention to who lies and their motivations to spread misinformation.
